I have a Panasonic LX1 (same as the Leica Digilux 2), and iView 2.64 will not read the RAW files. The Panasonic/Leica .RAW files from this 8 MP camera are about 16 MB each. I have been using the Adobe DNG converter, which is very fast. Once the files are converted with lossless compression the files are half the size at 8 MB, and now they are iView compatible. You can also sync your annotations to DNG without worrying because it's not a proprietary format.
